探索无限同轴端馈波导相控阵天线的替代配置。在所提出的配置中，端馈发射器和输出波导的集成，而不是波导本身，充当基本辐射器。这允许设计更紧凑的天线元件。为了分析和优化结构，开发了基于多模导纳矩阵表示的精确全波仿真工具。根据最先进的商业CAD软件对结果进行了验证。涉及单和双调谐配置的数值模拟和讨论，以说明所提出的配置和开发的CAD工具的潜在便利。© 2002 Wiley Periodicals，Inc.

An alternative configuration for an infinite coaxially end‐fed waveguide phased‐array antenna is explored. In the proposed configuration, the integration of the end‐fed launcher and the output waveguide, rather than the waveguide in itself, acts as a basic radiator. This allows the design of more compact antenna elements. In order to analyze and optimize the structure, an accurate full‐wave simulation tool based on the multimode admittance matrix representation is developed. Results are validated against state‐of‐the‐art commercial CAD software. Numerical simulations involving singly and doubly tuned configurations are presented and discussed to illustrate the potential convenience of the proposed configuration and of the CAD tool developed. © 2002 Wiley Periodicals, Inc.
